To perform any actions on Mergify, such as adding a pull request in a merge queue or triggering a command, a person must have sufficient access to the relevant account or resource. This access is controlled by permissions. A permission is the ability to perform a specific action. A role is a set of permissions you can assign to individuals or teams.

Mergify users inherit their roles directly from GitHub roles.

That means that a user that has the Read role for a repository in GitHub will also inherit this role in Mergify.

Managing IP Addresses Allowed for the GitHub App

Section titled Managing IP Addresses Allowed for the GitHub App

GitHub allows to configure the list of IP adresses that a GitHub App is allowed to use to access GitHub.

Mergify services do not use a single static IP address. Therefore, you must allow the AWS EC2 us-east-1 IP addresses.

This list can be retrieved on AWS website or via this command:

Terminal window
curl -s -o- | jq -r '.prefixes[] | select(.region=="us-east-1" and .service=="EC2") | .ip_prefix'
